FREDERICK Gr. LUMLEY, OF CHICAGO, ILLINOIS WINDOW VENTILATOR Appncaiion med April 1o, '1929. serialV No. 354,047.

My invention relates more particularly'to ventilators for use in connection with windows having vertically movable sash.

My objects, generally stated, are to provide a novel, simple and inexpensive construction of ventilator means; to provide a ventilator, the deflector of which may be readily applied to, and removed from, position at the window opening and which may b eadj usted with ease and preferably without previously manipulating fastening devices such as nuts or screws, to regulate the effective opening of the window below the inner sash; to provide a construction, the deiiectorof which may be adjusted to a position in which the windovsT opening is entirely closed in the open pos1-` tion of the sash, and which will not interfere with the free movement of the sash; to provide a construction, the deiiector of which will have the capabilities just described, but cannot be swung into the plane of'movement of the sash and interfere with the vertical movement .of .the latter and cannot acciden*v tally fall outwardly through the window opening; to provide asimple means for piv-V otally supporting the deflector for swinging movement and which will insure a dirt and rain-proof joint between the dei-lector and the sill of the window-frame; and other objects. as will be manifest from the following description. ,A A

Referring to the accompanying drawings s Fig. 1 is a face-view of a window-structure equipped with my improved ventilator means.`

Fig. 2 is a broken perspective view ofl oneof the lower similar corner-portions of' the window-structure showing the adjustable deflector member of the ventilator in closed position.

Fig. 3 is a brolrenview in sectional elevation through the deflector, at one end thereof,

,andthe adjacent'stationarystructure. Y

portion of which is shown at 8, the window casing being provided with vertically movable relatively offset window-sash, as is usually in windowstructures, the lower sash, represented at 9 only being shown.

The window ventilatorV comprises a deiiector member 10 of plate-like form, it being shown `as formed of a rectangular framell with an inset pane 12 of glass. The member 10 in use extends into the space between the sides 13 of the window casing and rests at its lower edge on the window sill 8, the mounting of the member 10 being such that it may be rocked upon its lower edge asY a fulcrum, toward and away from the sash 9, to close the opening below this sash when in partially raised condition, as for example, as shown in Fig. 1, or render it open to the room to a greater or less extent, as desired.

The fulcruming of t-he member 10 on the v sill 8 is aty a bead-forming portion 14 of the sill which extends lengthwise of the latter, is rounded on its Iupper surface, and extends into a1 groove 15 in the bottom of the member 10 and extending lengthwise of the latter preferably throughout its length, the bead 14 being preferably formed by a strip member separate from the sill 8 as shown and seated on the latter and securedfin place by a strip 16 set into a groove 17 in the sill and extending upwardly into a groove 18 in the bead 14, the fulcruming means thus provided forming a dust and water tight joint be- 9.5?

extends.

tween the member l() and sill 8, while permitting of the ready removal of the member 10 from operative position when desired as ereinafter described.

At each side of the window-frame 7 and between its side members 13 and the ends of the member l0, are brackets represented gencrally at 'i9 shown as in the form of segmentshaped plates 20, secured iiatwise against the side members 13, as by screws, one of which is represented at 2l.

The frontedges of the plates 2,0 are formed with inwardly extending flanges 221 disposed in the path of movement of the member 10 in the rocking of the latter in a direction away from the window-opening,namely .toward the interior of the room, and thereby form stops for the member 10. The upperL edges of the plates 2O are provided within Wardly extending arcuate flanges 23, the inner, edge portions of'whichareprovided with depending arcuate lia-leges 24, outwardly beyond-4 which the ends ofv the member 1D es tend rl-*he*upperec'geof; the member-10 ex,-

' tends above the under surface of the flanges 211s, except' at portions ofthe member L() registering withthepflanges 24, these portionsof the member lOlbeing recessed asy represented aty 255i of one end` of the member l0', with a metal insert 25. grooved at 27 tovreceive the flange 2a, these inserts being secured tothe member 1,0 as by the screwsf28f.l The member 1,0 is thus provided at opposite end s` with grooves on its upper,- surface, into which the flanges 24.., respectively, depend, thereby holding the member l() against, lengthwise movement while permitting it to. be; rocked on' its fulcrum, as desired.

The bracket members i9y are pnov-ided at the. upper ends of their rear` terminal portions, with stops (the stop for the bracket plate shown in Figs. 2 andfV 3l being repre.- sented at 29, Fig.v 7,) these stops extending into the path of movement of. the defiectoi;

1 member 10 in the movementl of the latter toward the window opening, and: are so posi,-K tiened as to stop the memberl() when its upperf edge extends just short; ofl the vertical plane in which theL inner face of thesash 9 Preferably the rear side of the deiector at its ends is recessed asfrepresented at 29a to compensate for the thickness of the stops 29g Thus,- the member` 10 may` be. swung to practically close the window,y open.

'- ing below the partially raised sash 9.

2). and without dangerof thel member 10, either dropping out of the window should the sash beraised above the position showin or obstructing the free vertical movementioff this sash.

The front end portions ofeach flange 23 isnotchedl as represented at SQl/tjo permitthemember 10 to be readily lifted out; of posif therein, as desired,

Means are provided for releasably holding the deflector member 10 in any one of the different positions to which it may be swung on its fulcrum, the particular means shown comprising a series of notches 31 in the under side of each flange 24, and balls 32 carried by the member 10, one at each end thereof, which are spring pressed upwardly to enter these notches and thereby hold the deiiector member l0 in adjusted position, the tension of the springs being such that the operator may, with. comparative ease, rock the deflector member 10intoY any one of the positions of adjustment provided for by the notches 3l.

The balls 32 are located in the faces of the recesses27andthus-within the confines of the front and rear faces ,of the member l0, so that the latter`- may be swung to a position in which thewindow opening below the sash 9 is practically closed as shown in Fig. 2.

The. bal-'lsv 32 areS shown, as Carried on the upper, endsoffstems which extendthrough openings 13e; in the bottomsogf. cupmembers located in openingj in the inset members 26 andhelld-in place by iiangesf. on the cup members., 35. engaging the masginal, edges of the opening 85 co'ilj springs,38A` for. pressing theA balls:V 32 intothe notches lsurrounding thestems SS-and locatedbetween the ballsl 32 and thej bottDmS 0f thecups. 85Y.

t is, desired that thev structure present a minimum amount of resistance to the swing,- ing. of they deflector member toward. the Window openingL and stllpresent; suiiieientresist, ance to hold. this, deiector: member, at all times, againsty acci dentalmoyement outr of ad,- JilSted position.y Accordingly I prefer to form the notches 3l of the shape shown, namely,topresent` relatively abrupt walls at the pontionstlieneof. farthestA from, the window y openingasrepresented at 39 and their opposingwa ls representedat l0 vmuch less abnupt, thev reason for providing relatively abrupt wallsf39 being to .insure the vdesired resistance t0 swinging moveinentof. the deflector mernber: l0 away fromtbe window opening in case ofa high pressure of. windL against themember 1.0- A

To permitvv the sash9, to be either raised or lowered fom thek positionshown in Fig, l,- the Window-lifts or handles would be locatedonthesidesof the sash at such aheight' above the top ofA the deflector 10 that they. will extend above the latter when the deflector is in the position shown inFig. l and the sash is lowered to close the window opening.

While Ihave illustrated and described a particular construction. embodyingmy invention, I' do not wish to-bevunderstood`- a-sintendingto limit it thereto as-thersame maybe variously modi-fied: and altered without departing from the spirit of my invention.
